China National Heavy Duty Truck Makes Heavy Weight to Create a World-Class Frame Assembly Workshop


“Offline! The first frame is off! We have succeeded!” On the afternoon of March 4th, people who had been fighting for 7 months at the newly-introduced electrophoresis line of China National Heavy Duty Truck finally saw it. The first carriage assembly that came down from the new electrophoresis line slowly went offline, and they shouted excitedly, with a long-lost grin on their faces. "The full commissioning of this electrophoresis line was successfully commissioned and officially put into use, marking a huge leap in the production capacity and quality level of China's heavy automobile rack assembly!

For more than seven months, the new workshop construction team has been struggling in the production line. They witnessed the land becoming dusty and clear; they witnessed each piece of equipment being assembled into giants by scattered parts; they played ingenuity, Make unfamiliar devices adapt to production needs in the shortest possible time...

Safe production is greater than days

They used their brains to carry out several transformations on equipment with potential safety hazards to protect the safety of operators and equipment. During the installation of the shot blasting machine, the mechanic made a slotted protective cover installed under the bearing to catch the sand, effectively preventing the sand from flying and avoiding damage to the motor and the operator. During the modification of the riveting line, the equipment installation team personnel changed the riveting line into a hard pipe, and also erected two seamless steel pipes, extending horizontally across the slide rails, and then with the high pressure oil pipe. connection. Effectively solves the problem of collision friction, prolongs the service life of high-pressure hoses and switch wires. It not only saves maintenance costs, reduces maintenance man-hours, but also eliminates potential safety hazards on the site. At the same time, the length of the tubing increases the working range of the riveting pliers. .

The finest quality control

The members of the equipment installation team are striving to achieve the most elaborate equipment after they are put into production. When debugging the shot blasting machine, the team's quality control personnel carefully studied the tail blow and they proposed a plan to replace the air outlet pipe with a thick pipe. After the implementation of the plan, the blast volume and air pressure of the shot blasting machine increased, effectively reducing the amount of sand carried by the stringer after tail blowing. In the second assembly workshop, before starting the trial operation, it actively established a quality monitoring system in line with its own production process. The detailed pictorial work instruction guide conveys the detailed image of each job to each employee, and solves the problems of difficult and unobvious results in the previous training process. At the same time, they sent employees from key positions to on-site training stations in the assembly shop to conduct on-site training so that they could master the operating points more quickly and accurately and enhance their skills.
The production site is picturesque

As the second frame assembly workshop is a newly built modern workshop, protection of the workshop production site during the production process is indispensable. In more than seven months, they organized countless arguments, experimented with various methods, and put forward optimization solutions for equipment installation. During the installation process of the punching machine, they absorbed the previous experience of installing the equipment and installed the wiring rack on the inner wall of the trench. The cables are fixed on the holes of the wiring rack so that the various cables can be seen at a glance. This not only makes the workshop look neat and beautiful, but also makes it easy to search for the required cables in the future.
On March 4, the first frame assembly produced by the new electrophoresis line was finally successfully off the assembly line. All employees of the frame factory knew that the downline of the first frame assembly means this new electrophoresis line. Coming soon to undertake large-scale production tasks will again be a severe test.
